Safari
CVE-ID: CVE-2007-4680
Available for: Windows XP or Vista
Impact: A remote attacker may be able to cause an untrusted
certificate to appear trusted
Description: An issue exists in the validation of certificates. A
man-in-the-middle attacker may be able to direct the user to a
legitimate site with a valid SSL certificate, then re-direct the user
to a spoofed web site that incorrectly appears to be trusted. This
could allow user credentials or other information to be collected.
This update addresses the issue through improved validation of
certificates. This issue is addressed for Mac OS X in Security Update
2007-008, and is incorporated into Mac OS X v10.4.11 and Mac OS X
v10.5 or later. Credit to Marko Karppinen, Petteri Kamppuri, and
Nikita Zhuk of MK&C for reporting this issue.

Safari
CVE-ID: CVE-2008-0050
Available for: Windows XP or Vista
Impact: A malicious proxy server may spoof secure websites
Description: A malicious HTTPS proxy server may return arbitrary
data to CFNetwork in a 502 Bad Gateway error, which could allow a
secure website to be spoofed. This update addresses the issue by
returning an error on any proxy error, instead of returning the
proxy-supplied data. This issue has already been addressed in Mac OS
X 10.5.2, and in Security Update 2008-002 for Mac OS X 10.4.11
systems.

page. By enticing a user to open a maliciously crafted URL, an
attacker may cause the disclosure of sensitive information. This
update addresses the issue by performing additional validation of
URLs. This issue does not affect Mac OS X systems. Credit to Robert
Swiecki of Google Information Security Team for reporting this issue.

Safari
CVE-ID: CVE-2008-1002

WebCore
CVE-ID: CVE-2008-1003
Available for: Mac OS X v10.4.11, Mac OS X v10.5.2,
Windows XP or Vista
Impact: Visiting a maliciously crafted website may result in cross-
site scripting
Description: An issue exists with the handling of web pages that
have explicitly set the document.domain property. This could lead to
a cross-site scripting attack in sites that set the document.domain
property, or between HTTP and HTTPS sites with the same
document.domain. This update addresses the issue by improving same-
origin checks. Credit to Adam Barth and Collin Jackson of Stanford
University for reporting this issue.

WebCore
CVE-ID: CVE-2008-1004

WebCore
CVE-ID: CVE-2008-1005
Available for: Mac OS X v10.4.11, Mac OS X v10.5.2,
Windows XP or Vista
Impact: Using Kotoeri reverse conversion on a password field
displays the password
Description: The content of password fields on web pages is normally
hidden to guard against disclosing it to others with the ability to
see the display. An issue exists with the use of the Kotoeri input
method, which could result in exposing the password field content on
the display when reverse conversion is requested. This update
addresses the issue by no longer exposing the content of password
fields when using Kotoeri reverse conversion.

Impact: Visiting a maliciously crafted website may result in cross-
site scripting
Description: The window.open() function may be used to change the
security context of a webpage to the calleris context. Enticing a
user to open a maliciously crafted page could allow an arbitrary
script to be executed in the useris security context. This update
addresses the issue by not allowing the security context to be
changed. Credit to Adam Barth and Collin Jackson of Stanford
University for reporting this issue.

Available for: Mac OS X v10.4.11, Mac OS X v10.5.2,
Windows XP or Vista
Impact: Visiting a maliciously crafted website may result in cross-
site scripting
Description: A JavaScript injection issue exists in the handling of
the history object. This may allow frames to set history object
properties in all other frames loaded from the same web page. An
attacker may leverage this issue to inject JavaScript that will run
in the context of other frames, resulting in cross-site scripting.
This update addresses the issue by no longer allowing webpages to
alter the history object.
